Question

Archimedes' principle says that a 15 N object is buoyed up by a force that is

Answer 1

an immersed object is buoyed up by force equal to the weight of the fluid it displaces

Answer 2

• equal to the weight of the fluid that the body displaces

Step-by-step explanation:

Archimides' principle states the definition of buoyant force.

These are the imporant features of the buoyant force that you need to know:

• Except for the very special vacuum condition, every body is immersed in a fluid.

• The body is subject, at least, to two forces, its weight and the buoyant force.

• The weight is the result of the gravitational attraction exerted by the planet, and is equal to the mass of the object by the gravitational acceleration (approximately 9.8 m/s² on Earth). It is directed vertically downward.

• The buoyant force is the vertical upward force that the fluid exerts on the object and is equal to the weight of the volume of fluid displaced by the object.

• The volume of fluid that the body displaces is equal to the immersed volume of the body.
